# Advanced settings

The **Advanced Settings** tab in the **ExtensionsManager** allows administrators to modify the **global configuration** that applies to the entire environment and all extensions.

From here, you can update settings such as:

* **Port** – Change the port number used by the ExtensionsManager.
* **HTTPS and Domain** – Enable secure connections and define the domain used by the ExtensionManager
* **TREX URL** – Configure how `.trex` files are generated when running behind a reverse proxy or using a custom domain.

***

#### Editing Your Configuration

You have **two ways** to edit your configuration:

1. **Edit Individual Settings**\
   Modify each setting (Port, HTTPS, or TREX) separately.\
   This is recommended for **advanced users** who only need to adjust one or two parameters.
2. **Wizard Mode**\
   Use the **Configuration Wizard** to set up all global settings at once — just like during the initial installation.\
   This is recommended for **new users** or when performing a **full reconfiguration**.

Using the Wizard will **reset all global configuration settings**
